Questions were raised in the Rail Accident Investigation Branch's (RAIB) year-long investigation into the crash as to how the safety of the tram network was managed.

One of the RAIB’s recommendations was for TOL to review areas such as how to create a “just culture” after drivers did not report issues to managers because they “feared the consequences” for themselves if they did so.

This led to TOL not understanding the extent of late braking, the report states, and therefore took no action to mitigate the risk.

It also found that TOL did not fully investigate an incident where a driver nearly derailed a tram on the exact same bend as the fatal crash and the RAIB also brought into question TOL’s fatigue management procedures.
